Competency 15 Patterns and Algebra

True

True or False?

Only like algebraic terms (same exponent) can be added or subtracted to produce a simple expression

Ex: 2x3 and 3x3 = 5x3

True

True or False?

Multiply the constant term and add the exponents.

Ex: 4w2 x 8w3 = 32w5

True

True or False?

When dividing algebraic terms, always subtract the exponents.

Ex: 2x7 / 5x3 = 2x 7-3 = 2x4/5

     

Non-Linear Function
Function graphed as an unstraight line
Linear Functions
Functions graphed as a straight line
Expressions

Group like terms together when solving these

 

Ex: 3x+4-2x+1 = 3x-2x + 4+1

x=5

Ordered Pairs
When graphing these, move horizontally 1st then move up or down vertically to the 2nd number
Equations

When solving these, perform the invrse operation to get the vaiable by itself.

 

Example:

t-5 = 27

t-5+5 = 27+5

t = 32

Y-Axis
The line that goes up and down, the vertical line is the
X-Axis
The line that goes left to right, the horizontal line is called the…
